Light & Nutrient Timers

Hydroponic timers for your Hydroponic grow lights and for the Hydroponic nutrient pump make Hydroponic gardening so much easier. You can make almost everything within the Hydroponic system automatic.

You still have to monitor the Ph and PPM of your Hydroponic nutrient solution and make adjustments up or down when needed but the feed times and duration along with the grow lights coming on and going off is fully automatic when you install good timers in your Hydroponic system.

Some larger commercial Hydroponic operations actually have monitors and alarms installed to monitor Ph and PPM of their nutrient tanks. Smaller Hydroponic systems rely on human monitoring of these things, usually checking these things on a daily basis.

To make our Hydroponic gardening system fully automatic we will need a timer for lights and also a timer for the Hydroponic nutrient tank pump. If you already know what you will be growing and what kind of Hydroponic system you will be using that will help a lot with choosing the right timers. Knowing what our Hydroponic growing medium will be helps even more.

This simple timer here is by Intermatic and is really all you will need to control most Hydroponic grow lights. You can find this and similar type timers in most hardware stores or even in department stores.This particular model has up to 3 on and off settings per day and for your Hydroponic grow light you will just be needing 1 on and 1 off setting per day. Try to get a timer that is rated heavy duty (15 amps or more) and has a 3 prong grounded outlet. Any timer that is rated for air conditioners or appliances should be fine. You will be setting your light timer for about 18 hours on and 6 hours off. That can change at blooming time to about 12 on and 12 off if you are growing crops that flower.
